Chem-Free Holding Tank Bill Goes to Gov

CalARVC logoThe California bill, AB 1824, that would ban the use of many holding tank chemicals, is swiftly on its way to its final destination – the governor’s desk.

The California Association of RV Parks and Campgrounds (CalARVC) is urging California campgrounds to write Gov. Arnold Schwarzenegger encouraging him to sign the bill into law.

AB 1824 has made its way almost unanimously through both Houses and their respective committees with only three nay votes and one abstention, CalARVC reported. The law is meant to protect campground owners and millions of campers from the assumed negative effects from products that contain bronopol, dowicil, formaldehyde, glutaraldehyde, paraformadelhyde and paradichlorobenzene.

Background

Ann Arbor, Mich.-based Thetford Corp., a manufacturer of holding tank chemicals for both the marine and RV markets, Dometic Corp., Elkhart, Ind., a Thetford competitor, and the Recreation Vehicle Industry Association (RVIA) opposed the bill – essentially urging the state of California to back up their reasons with science that proves these chemicals are fouling up septic systems.

Thetford contends that use patterns – the fact that many people often dump holding tanks in a short period of time – is a more serious root cause of septic system problems.

“We do not feel that we have been shown any science that shows that the six chemicals that are being banned are going to address the problem,” said Diane Farrell, RVIA vice president of government affairs. “It seems like a remedy and yet we have not seen the right data pointing us to the problem at hand. California is a leader in the green movement, and one of the premises of that is to get chemicals into the hands of the scientists and this seems to be avoiding that process.”

CalARVC was unswayed by Thetford and RVIA’s opposition, and Dometic’s request to pull bronopol from the bill.

“Dometic has put a letter in opposition suggesting that bronopol be pulled from the bill and that is when we had to dig deeper into the science,” explained Debbie Sipe, executive director for CalARVC.

According to Sipe, the California Department of Toxics and Substance Control has looked into this question, but is coming up with inconclusive results.

“Fundamentally all chemicals, even green chemicals, have a risk associated with them,” explained Ed McKiernan, Dometic director of development for product sanitation at Dometic’s plant in Big Prairie, Ohio. “When you ban chemicals and just say ‘this is banned,’ you don’t know what all the consequences could be. In the case of this law, one of my biggest fears is that it is going to cause more difficulty and more harm to campground septic systems than if the law didn’t happen.”

In fact, McKiernan claims banning these chemicals, which come from a list assembled 10 years ago by Katherine Farrell-Poe, PhD, of the University of Arizona, will have virtually no positive effect on the environment.

“The level of bronopol that is used in a 40-gallon tank will virtually have no impact on a septic system based on studies that have been done at sewage treatment plants,” McKiernan explained. “At the time the list was put together it was thought that bronopol was another name for formaldehyde, and it’s not. There has been a lot of research done and it is clearly a different product. Bronopol is a good chemical because it is cost-effective, does a good job of odor control at high temperatures and has very minimal environmental impact.”

McKiernan said RV owners can – and often do – use alternative products that contain ammonium compounds, calcium nitrates or enzymes/bacteriological kinds of additives.

“The difficulty with those three alternatives is there are issues with biodegradability and odor control,” he said. “Nitrates are not removed when they go to the septic tank. They go into the leach field. You are going to be adding more nitrates and causing a bigger problem for the environment.”

Some of the greener products generally don’t work at high temperatures, according to McKiernan, and in the state of California where high temperatures are the norm, he maintained, fighting bad odors could become a way of life for the RV enthusiast.

When you take away products containing bronopol, McKiernan maintained, RV owners will likely start using homemade concoctions containing things like Drano or bleach, which kill all the bacteria in a septic system. “This will have a very negative environmental effect,” he said.

“We want to do the right thing environmentally, but we want to do the right thing by giving the RV owner products that work in high temperatures,” McKiernan added.

McKiernan would like to see California do an in-depth study on bronopol to gain a clearer understanding before passing the bill as it stands.

    That’s just like Cal. Passing Laws with out all the facts, Just like gold Dredging they banned, They believed the Green Weenies false facts and didn’t wait for the real facts before banning gold dredging all together.What made Cal. Gold Prospectors

    Good for Calf. I have known for years that these additives would cause problems There are diffrent products out there that work and are not toxic but the big guys are so intrenched in the market they keep out the comp.
    Also people want it cheap the little bit they use that hurts the enviroment is small this justifies the use to them. Calf has looked at the big picture the totals.
    Question: what do the porta potty guys use and i guess the boater will also get hit on this if it comes down
